  The paper presents quasi-static 3D buckling analysis results of thin-walled cylindrical metal silos with and without bulk solids. The behaviour of the bulk solid was described with a hypoplastic constitutive model. Non-linear analyses with geometric and material non-linearity were performed with a perfect and an imperfect silo shell. Different initial geometric imperfections were considered. The influence of internally stored bulk...

  - THIN-WALLED STRUCTURES - Year 2023

  The results of experimental and numerical tests of a single corrugated sheet silo column’s buckling resistance are presented in this study. The experiments were performed in a real silo with and without bulk solid (wheat). A very positive impact of the bulk solid on the column buckling resistance occurred. The experimental results were first compared to the buckling resistance calculated by Eurocode 3 formulae. The comparison revealed that...

  - PARTICULATE SCIENCE AND TECHNOLOGY - Year 2016

  The paper presents 3D results on stability of thin-walled cylindrical metal silos made of isotropic rolled and corrugated plates containing bulk solids. The behavior of bulk solids was described using a hypoplastic constitutive model. Nonlinear finite element (FE) analyses with both geometric and material nonlinearity were performed with a perfect and an imperfect silo shell wherein initial geometric imperfections were taken into...

  Background Due to important role of metals in the vinification process as well as their impact on the human health, their content in this alcoholic beverage has been extensively studied by many researchers. It is already known that speciation of metals determines their toxicity and bioavailability as well as influences their activity. Understanding the chemistry and knowing the structures of metal complexes could have relevant...

  W artykule symulowano proces wyboczenia w cylindrycznych metalowych silosach z płaskich blach wypełnionych materiałem sypkim. Wykonano analizy nieliniowe stosując MES dla silosów pustych i napełnionych. Zbadano wpływ wstępnych imperfekcji geometrycznych na nośność wyboczeniowo. Wyniki porównano z wynikami doświadczalnymi w Uniwersytecie Karlsruhe.
